Furthermore, considerable phenotypic overlap between albinism and other conditions such as foveal hypoplasia 2 (FVH2, OMIM #609218, also known as foveal hypoplasia 2, optic nerve decussation defects, and anterior segment dysgenesis (FHONDA) syndrome) caused by SLC38A8 mutations may also confound the diagnosis. Here, SLC38A8 is linked to Foveal hypoplasia-optic nerve decussation defect-anterior segment dysgenesis syndrome.
